Swanson and Allison V. Covert while visiting a property owned by Katherine J. Hahn. By late Sunday it was arranged that pre-scheduled viewing would be possible on Monday and Tuesday (October 25 and 26). I volunteered to act as the "host" for Tuesday morning. I arrived at 8 am with Colin D. Jones and Krysten Martin was there at the same time. We began searching for the bird and at about 8:40 Colin found it, foraging in the grass. I stayed until noon and never lost sight of the bird for more than about ten minutes. It would spend periods of 10-20 minutes very actively foraging in the long grass under the conifers and next to the pasture, sometimes quite close to those people watching it. After a while of foraging it would sit either in the grass or in a tree for ~5-10 minutes resting and sometimes very actively preening. It worked it's way north up the hedgerow right to the road, at one point flying out over the road briefly then turning back and then worked it's way south. By noon it was at the south end of the hedgerow. I did hear the bird vocalize the same call about half a dozen times; each time it repeated the call ~4-5 times in fairly quick succession. I did make a recording of the first sequence, which captures two calls.] 2) Description [Grackle-sized all black bird. Very long-tailed, with a very heavy bill. Bill had 3 parallel grooves on upper mandible and two very faint grooves on the lower mandible. Eye was dark. Head, nape, upper back and upper chest feathers tipped with lighter blue-grey colour.] 3) How were similar species eliminated? [From Smooth-billed Ani by presence of obvious grooves on upper and lower mandible.] 4) Experience with claimed species [I saw about 30 while driving through Costa Rica in 2011 and I've seen Smooth-billed Ani about 20 times in Ecuador, Panama, Dominican Republic, and Cuba.] 5) Field guides/references consulted [I consulted Pyle's "Identification Guide to North American Birds, Part 1" and Steve Howell's "Molt in North American Birds" to better understand the molt and plumage of this bird.] 6) Any additional commentary/analysis [The bird had an obvious molt limit in the wing and tail: there was a small block of retained brownish (juv) feathers in the three of the inner secondaries and two or three outer primaries. The outer 2-3 tail feathers on each side of the tail were similarly worn and brownish. I take this to mean this is a bird which has begun, but not completed its preformative molt, which apparently is fairly common (Pyle, Howell). ] Description made from memory.
